Following February 2014 and July 2015, the State Grid Corporation won the bid for the Brazilian hydropower beautiful mountain HVDC sent a second phase of the project, in December 2015.
It is currently Africa's longest transmission line, the highest voltage level, transmission capacity the largest power transmission project - Ethiopia GDHA500 kilovolt power transmission project completed, marking the Ethiopian era into a 500 kV voltage level, China and the Chinese standard equipment successfully into Africa, marking the Chinese EHV transmission technology, equipment and engineering total contract "going out" a major breakthrough.
The project is the revival of the Nile dam hydropower transmission project, including the new 2 × 620 one thousand meters of 500 kV double-circuit line with towers and a total length of 98 km double-circuit 400 kV transmission line, the new De Desa, two Huolai Ta 500-kilovolt substations, expansion of three 400-kilovolt substations, the transmission capacity of six million kilowatts, the total investment of 1.458 billion US dollars.
Works by China's State Grid Corporation of power equipment general contracting construction company, all Chinese-made electrical equipment, construction heavy use of Chinese technology standards, is to implement the national "along the way" model project strategy and international production cooperation.
Engineering built the largest so far in Africa 500 kilovolt substation and switching station, but also the national grid company is currently in the completing of the scale of overseas investment and the largest power transmission project. Ethiopian project will not only improve the power grid structure, the Ethiopian capital to resolve the power shortage problem areas play a significant role but also to promote clean energy delivery and Ethiopia to build global energy internet are of great significance.
Project is located in the East African plateau, across the board average elevation of over 2300 meters, crossing the no man's land, construction to complex geological structure, expansive soil and widespread volcanic lava, the hot, rainy season for a long time, we need to overcome long front, harsh environment, the number of devices and another negative factor, extremely difficult.
Since the project started in March 2014, the power equipment company under the State Grid Corporation of leadership, strengthen project coordination and scheduling organization, established business, contracts, taxation, planning, safety and quality, supplies, manpower allocation, Healthcare 8 a security system, has organized domestic and foreign design, supply, construction, supervision, commissioning, more than 110 construction units and nearly two million Chinese and foreign power builder, after 21 months of hard work, finally built a safe, reliable, independent innovation, economical and environment-friendly, world-class quality engineering.
"Practice has proved that the electrical equipment company is a trusted partner! They are in short duration, large projects, environmental strange situation, the successful completion of construction tasks, the State Grid Corporation has a proven excellent project management capacity-building and strengthening sincere willingness for bilateral cooperation. "Ethiopian Electric Power Company president power equipment for the company's performance to give a positive evaluation.
